The 70th wedding anniversary is known as the platinum anniversary and that color can be used as its theme. Platinum is a light metallic gray. It typically has a more bluish tinge than silver.
The traditional gift for a 70th wedding anniversary is platinum jewelry. For those on a budget, gifts can be wrapped using platinum colored paper and ribbons instead. Family and friends can host a party for the couple using platinum as the color of balloons, streamers and tablecloths. An accent color, such as orange, can have a striking effect. Other options to celebrate a 70th anniversary include engraved photo frames, a second honeymoon and a slideshow.
